This patch adds a new optional arch specific API to /proc/bus/pci to get at
legacy I/O and memory space. I know most platforms will correctly route
legacy I/O and memory accesses to some well defined bus, but some don't (I
think some PPC machines fall into the latter category?), thus the need for
this patch. I've also included draft documentation for the /proc/bus/pci API
in general since it didn't appear to be documented anywhere but in the
source. Comments? I'm successfully using this to bring up gfx stuff (i.e.
card POSTing, X) on an Altix machine.

Thanks,
Jesse
